    • addInvalidationListener

      public void addInvalidationListener(Runnable runnable)
      Description copied from interface: IHolderSetExtension

      Adds a callback to run when this holderset's contents invalidate (i.e. because tags were rebound).

      The intended usage and use case is with composite holdersets that need to cache sets/list based on other holdersets, which may be mutable (because they are tag-based or themselves composite holdersets). Composite holdersets should use this to add callbacks to each of their component holdersets when constructed.

      Specified by:
      addInvalidationListener in interface IHolderSetExtension<T>
      Parameters:
      runnable - Runnable to invoke when this component holderset's contents are no longer valid. This runnable should only clear caches and allow them to be lazily reevaluated later, as not all tag holdersets may have been rebound when this is called. This runnable should also invalidate all of the caller's listeners.
